Ferrite Ring Core Black RFI EMI Noise Suppressor Cable Clip-20Pcs

I was having issues with interface due to my 2.4 ghz wifi, which I was able to determine by selectively turning it on and off. I could negate the inerfence by turning the network off, but there are devices tht depend on the signal at that range, so I reduced its power, but it still gave an awful sound on mic to the point it was unusable.These little cores snapped right on without issue. I'll have to see how well they stand up. I put 3 on my cord: near the mic, in the middle and near my computer. I no longer have any interference! So I can't be any happier.

Perfect item

I bought these to try and fix a CB radio that had intermittent poping noises coming from the speaker. I put them on both the power wire and the antenna wire, but it did not fix the issue. It could be a problem inside the CB unit itself, so I'm not saying that these do not work, they just didn't work for me. They do seem like a high quality product and the various size options are nice to have.

I bought these because I had some sound interference on one of my GMRS radios I was getting some alternator wine because I had this plugged in through my 12 V cigarette lighter power source in my truck. I used a couple of these and the noise.

After putting new LED fog lights in I noticed interference in radio reception I heard about these and decided to try was very happy with the results

I've been trying to get a better signal on a few of the channels I get with my TV antenna. Any signal improvement can help the quality, pixelating and the number of stations received. So I saw how chokes can remove certain kinds of interfering signals, and tried these. In the morning, I ran a channel scan, and got 59 stations. I put a ferrite choke on the coax, right before the amplifier (did not want to amplify interference), and a second scan a minute later gave me 65 channels. I've found a cable splitter, and a lightning arrestor/5g filter both dropped 90% of my channels. I can't use them. Only the strongest signals made it through. I saw the antenna expert show how the longer your coax is, the bigger the signal drop. And even just coiling excess coax will also result in a signal drop. I know now, that even a small drop in signal can be the difference between getting 60 stations and 12. Next step is RG6 quad coax, and it being just long enough to reach. I have a 70 mile omni directional antenna, and an 80 mile directional with vhf to reach a specific far away station. Very happy cutting the cord, and happy with these chokes. By the way, with a good antenna signal, the picture is much better than a cable signal. Cable compresses their signal. and when you get it, its only a fraction of what the signal was originally.

After installing several of these, it was clear that they didn't work. Very disappointed.

I tried it on cable for a two-way radio and didn't seem to make much of a difference I didn't return the item cuz I want to keep trying
